over boost?

[COMEgetusum]

when im at full throttle my service light comes on then turns off when i let off, i thought maybe it was over boost but the other day it did it when i wasnt even gettin on it any ideas?

Probably the HPOP not keeping up with demand. If you were overboosting >24psi, the truck would defuel. To know for sure, you need to pull the codes with a good scanner.

My friend's 6oh can boost up to 32 psi what could cause it. Is it programed or vanes sticking.
I warned him not to overboost past 23 psi.

The 6.0 is vary different from the 7.3. You would have better luck asking in a 6.0 forum.

Chiped truck is going to make enough boost to make cel come on mine does it all tge time and it damn sure dont defuel.lol. More fuel = more boost.

Depends on the tuner, some can remove the codes but a stock truck or one with a generic tune such as bully dog should hit it's limit around 24psi and defuel. Regardless, you need to pull codes to know for sure.

ya i dont really know what may be causing it because the oil pressure is fine, my number 8 injector is going out could that cause it possibly?

[JSchuricht]

Are you measuring oil pressure with something other than the idiot gauge on the dash which only measures low pressure oil? Your injector could be part of the problem, causing the more oil use than normal resulting in a light for low oil pressure. We can only guess till you check your codes..

my only codes are p2060 and p1316 i know 1316 is a idm code but im pretty sure its just the harness i hear those go bad quite often im not sure about the other one i think it has somethin to do with the intake

[JSchuricht]

Did you pull the code while the light was on or after the fault cleared?
